Since then, Khloe has remained by the side of her estranged husband, rarely leaving his hospital bed and even moving Lamar into a rehab facility near her home in Calabasas.

In the emotional moments after Khloe learns of of her Odom's serious health crisis, the 31-year-old star appears completely stunned in the following footage, as the camera zooms in on her pale, expressionless face.

"Khloe has been spending every second with Lamar," Kourtney Kardashian, says in the trailer, while mom Kris Jenner, can be heard off camera, telling her daughter at one point:

"I think hearing our voices and having family around might make a difference."

Odom only had a 50% chance of survival in the first few days after his overdose, but he has since overcome the odds and will likely make a full recovery.
